f As is well known to those skilled in the art it is frequently necessary to place the cocks of hydrants 'at considerable distances below the surfaces of the ground where they will not be subjected to freezing temperatures.

This is particularly true where hydrants areV used in railroad yards, stock yards and the like. It has been the practice to operate these cocks by means of rods adapted to be inserted downwardly intoVA openings or recesses and 15 into engagement with the heads of the valves. Each valve has supported the weight of the Vrod but the construction hasV been objectionable because, should a heavy object be dropped n on the upper end ofthe rod or drawn therethe rod would be forced downwardly to such an extent as against its seat. Therefore been impossible to turn the valve away vfrom the position in which it has been jammed,

.pag.25 any'efl'orts along this line resulting inv twistyment which can be applied readily to hydrantv cocksalready on the market and can be operated by the usual rod or other means-employed for that purpose.

With the foregolng and other objects in view which will appear as the description bination and arrangement of parts and in the details of construction hereinafter'described and claimed, it being understood that changes inthe precise embodiment of the invention Y, 7 '50 lherein disclosed may be made within the to tightly wedge the valve' it frequently has proceeds, the invention resides in the comf through# the block scope of *what is claimed, ,without departing from the spirit of the invention. y -A In theaccompan'ying drawings, the preferred forms' of ythe inventionhave been shown. .-5 j Y"In-said d`rawi1'1'gs,f1 Y 'f Figure l is an elevation. of ahydrant' cock located below. the surface ofthe ground and y providedlwith'the'attachmentxconstituting the present improvement, said attachment being '1 'engaged-"by an operating member extending above'theA surface ofy the ground. f r A lFigure 2 is an elevation of ahydra-nt cock, theattachment thereon being shown `insection... f ff' ment.
